IMPROVEMENT IN PRESSES FOR HOLDING BOOKS.

Specification forming part of Letters Patent No. 143,410, (lated October7, 1873 application filed August 9, 1873. i

To all whom it may concern:

Be it known that I, LOUIs HEITKAMP, of the city, county, and State ofNew York, have invented a new and useful Improvement in Book-HoldingPresses, of which the following is a speciication:

Heretofore, in marbling the edges of books, a row of books had to beheld together by hand while their edges were being dipped, therebygiving the color and gum a chance to soak into the leaves of the booksif the paper be not sufficiently hard; and it is well known thatengravings are frequently printed on soft paper 5 and the tissue-paperused in protecting such plates, and bound into the book, is also of asoft character, and apt to soak upthe color. This can be avoided bysubjecting the books, while being dipped,'to a greater pressure thanwhat can be given by hand. For that purpose I have constructed asuitable press, of light weight, to compress a row of books, dip thethree edges of the books while in the press, and leave them in the pressuntil the color has sufficiently set.

Figure l is a side view of the press; Fig. 2, an end view; Fig. 3, across-sectional view thereof, showing the shape of the platen 5 Fig. 4,a side view of the press having a row of books inserted; Fig. 5, a frontview, also with the books inserted, ready for dipping.

The press consists of two end plates, a. a', being connected together byfour rods, b b and c c, each having a nut at both ends. The nuts d d atthe ends of the rods b b serve to keep the two end plates ce a apart,being at the inner sides ofthe said plates, and the nuts e e of the rodsc c, being at the outside of the end plates, hold the said plates inposition. The

end plate a is furnished with a female screw thread, through whichpasses a screw, f, havin g a hand-wheel at its outer end, by which itcan be turned. The inner end of the screw f bears against the platen orfollowing-board g, to which it is so affixed as to slide it back andforth, the platen being guided by the rods c c, as seen in Fig. 3. I

The pile of books, as shown in Figs. 4. and 5, at h h L, is placedbetween the platen g and the end plate al, with their backs toward therods c c; and bevel-boards k k are inserted between the books and theplaten, and between the books and the end plate a', as shown in Fig. 4,the thick ends toward the front edge of the books, so as to insure thecompactness of the edges. Now, pressure being given by means of thescrew j', the books are ready to be dipped without incurring the risk ofthe color soaking into the leaves.

As it is desirable that the whole apparatus should be as light aspossible, I make the end pla-tes a a', and also the platen g, of wood,and the rods b and c of metallic tubing'.

I am aware that clamps or presses are being used in various stages ofthe manufacture of books; but I do not know of any now in use. thatcould be adapted for the work for which l have devised theabove-described press; and

I claim as my invention- A press consisting of the two end pieces al a',rods b and c, screwf, and follower g, substantially as and for thepurpose specified.
